'3 Claims. 1

This invention relates to roller wound window coverings such as-screens and storm windows of flexible glass or other flexible material, and aims to provide certain new and useful improvements whereby the applicability and practability of mounting such coverings on windows and the operation thereof are very substantially enhanced.

Another object of the invention is the provision of novel and practical vertical guides on the window frame for the side edges of the roller wound covering, and in combination therewith novel means for locking the edges of the covering when the covering is in the extended position over the window opening, the locking means being readily releasable for rewinding the covering on the roller.

The above as well as additional and more detailed objects will become apparent in the following description, wherein characters of reference refer to like-numbered parts in the accompanying drawing. It is to be noted that the drawing is intended for the purpose of illustration only and that it is neither desired nor intended to limit the invention to any or all of the specific details of construction shown, excepting insofar as they may be deemed essential to the invention.

Referring briefly to the drawing,

Fig. l is a front elevational view of a window frame, showing the invention applied thereto.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on the line 33 of Fig. 1, showing the edges of the screen in locked position.

Fig. 4 is a sectional view taken on the line 44 of Fig. 1.

Fig. 5 is a view similar to Fig. 3, showing, however, the edges of the screen in released position.

Referring in detail to the drawing, the numeral l0 indicates a window having the side rails I I and I2. A roller IS, having a spring 13a normally urging the roller to wind up, and similar to a window shade roller except that it need not be provided with the usual ratchet and pawl, not shown, is mounted in the usual manner in brackets [4 on the top of the window frame. In the drawings a window screen !5 is shown wound on the roller I3, but of course a sheet of flexible glass or other flexible or transparent material, not shown, might be substituted for the screen to serve as a storm window.

On each of the side rails I2 and !3, right next to the sash guide groove 5, a longitudinal strip i! is secured against the side rail, as bymeansiof second longitudinal strip I9 is likewise secured as by nails It. These strips extend the entire length of the window opening.

A longitudinal groove 29 is provided on the inside of the strip I "l, and a complementary longitudinal groove 21 is provided on the inside of the strip l9; thus, if the two strips l1 and I9 are considered as a unit, the combined strip ll-IU may be said to have a longitudinal groove 20-2l extending down the middle thereof.

The groove 26 is provided with a right-angled portion 22 and a concave portion 23; the groove '2! is provided with a concave portion 24 opposite the right-angled portion of the groove 20, and with a straight flat portion 25 opposite the open length of the groove 202l.

A pivotable member 26 extends the entire length of the strips ll-l9 and registers in the groove 2fi-Zl. The member 26 has a rounded base portion 21 which registers in the rounded portion 24 of the groove 2| and is pivotable in the said portion 25. The member 26 has a longitudinal cam-like tongue 28 extending the entire length of the member, whose edges 29 and 30 are substantially flat.

The lateral edges of the screen l5 register loosely and slidably in the groove 20-2I, as shown in Figs. 3 and 5, between the tongue 28 and the groove 26. It is apparent that when the member 26 is swung from the position shown in Fig. 5, wherein the screen is free to move up and down, to that shown in Fig. 3 wherein the edges of the screen are clamped by the tongue 28 against the strip ll, the screen is stopped securely in Whatever position it has been lowered or raised to.

Each strip i9 has, intermediate its length, a transverse slot 3! cut therethrough into the groove 2!, through which a handle 32 extends, the handle being secured to the member 26. Thus, by grasping the handle 32 the member 26 may be swung in the manner above described.

A reinforcing strip 33 may be provided along the lower edge of the screen I5, as well as a hand grip 34. It is to be understood that wherever the member It has been referred to as a screen, it might just as well be any other form of flexible Window covering such as above-mentioned.

Obviously, modifications in form and structure may be made without departing from the spirit and scope of the invention.

Iclai'm:

1. In a window frame having a spring actuated roller mounted at the top thereof and having a sheet-like flexible window covering wound thereon, a vertical strip secured against one side rail of said frame, said strip having a vertical groove extending substantially the entire length of the strip, said groove being substantially in alignment with said covering and having an edge of said covering registering slidably therein, said groove having a concave cylindrical surface, a vertical member of lesser cross-sectional area than that of said groove, pivotally mounted in said groove and extending substantially the entire length of said strip, said member having a cam-like longitudinal tongue extending therefrom, the lateral edge of said covering being positioned between the cylindrical portion of said groove and said tongue, said member being rotatable in one direction to clamp said lateral edge between said tongue and said cylindrical portion and rotatable in the opposite direction to release said lateral edge.

2. The device set forth in claim 1, having means for rotating said member as aforesaid, said means 20 Number comprising a hand grip secured to said member intermediate the length of the member, said strip having a transverse slot intermediate its length extending into said groove, said hand grip extending through said slot.

3. The device set forth in claim 1, at least a portion of the surface of said groove opposite said cylindrical portion thereof having a concave cylindrical surface, said vertical member having a substantially complementary convex cylindrical surface registering loosely in said concave portion of said groove.
